IMPROVEMENT IN FLY-TRAPS.

Specification forming part of Letters Patent No. 146,194, dated January 6,1874; application filed i September 20 1873. i

To all whom itmmay concern:

Beit known that we, N. BARKER MGOEEARY and HENRY L. GRIsT, of Phelps City, -in the county of Atchison and State of Missouri, have invented a new and Improved Fly-Trap, of which the following is a specification:

In the accompanying drawing, Figures 1 and 2 represent, respectively, vertical longitudinal and vertical transverse sections of our improved ily-trap on the lines w w andyy.

Similar letters of reference indicate corresponding parts.

Our invention is an improvement in the class of insect-traps formed of an inner and outer Wire-gauze cage. The invention consists in the construction of the inner cage, and the means of attaching the same to the outer cage, as herein described.

In the drawing, A represents the outer cage or cone, which is made of wiregauze, in the shape of a truncated pyramid, having the top rounded oft'. The sides and bottom edges of cage A are connected by suitable linings a, 0f tin or other sheet metal, producing the required strength and durability of the cage. The interior cage, B, is formed of a plate or sheet of wire-gauze, which is cut to the required size and shape, (rectangular,) and has small conical projections C, with openings c, formed by stretching the material along the transverse middle of the plate. The edges are bound or inclosed by sheet-metal strips d, so that whenthe plate is bent and placed in the cage A said edges come into close contact with the inner sides of the latter, thus preventing escape `of the flies from the upper chamber, into which they pass through the opening e.

` shown.

The outer cage, A, rests on the cross-barsf of a bait-pan, D, which is of sufficient depth and width to extend around the base of cage A, and admits easily the nies to the baitat the bottom thereof, from which they pass through the cones C into theA upper chamber,

where they are killed by hot water, heat, or

other 4suitable means. A small door, E, is hinged at one side, near the top part of cage A, and serves for the purpose of removing the iiies without detaching the inner cage, B.

The simple construction of parts allows the` manufacture of these iy-traps at smallcost and at any place.

Having thus described our inventiomwe claim as new and desire to secure by Letters Patent- In combination with the cage A, the inner cage, B, formed of a bent and apertured wiregauze plate, B, the latter being` connected to and supported within the former by the catches b, as shown and described.
